HITH is caused by poor water quality. Technically angels' aren't as frail as some other fish, so as long as you check your water conditions weekly and do weekly 30% water changes, you should be ok. Remember that if there is a problem ( High Ph, Low Ph, High Nitrate, Ammonia) fix it.
I sound like i'm forcing you to keep angels, lol.
Hmm, Festivums are VERY neat fish. You could have maybe 4 max in your tank.
